Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

Rockchip RK3399 Benchmarks Appear on GeekBench

Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner. We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench. The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. I’m not that familiar with GeekBench so number don’t tell me anything. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes. There’s a significant single-core performance boost (+73%), and lower […]

Coowell V4 Android TV Box Review – Part 2: Camera, Skype, Google Hangouts and Duo

Coowell V4 Android TV box is based on Rockchip RK3368 octa-core processor with 2GB RAM, and 16GB flash, and also includes a camera. In part 1 of Coowell V4 review, I have already taken photos of the device, and torn down the device to have a closer look at the board, and the camera which is based on a GC2145 2MP image sensor. Today, I’ll mostly test the camera and microphone, including firmware compatibility with Skype, Google Hangouts, and the latest Duo by Google app. Finally, it’s been a while since I’ve tested a RK3368 TV box, so I’ll run CPU-Z and Antutu again. Coowell V4 Hardware Setup and Launcher Coowell V4 hardware setup is pretty usual, and I connect an Ethernet port, and the USB RF dongle for MINIX NEO A2 Lite air mouse, as well as a USB keyboard to take screenshots. However, while normally I’d use my […]

Coowell V4 Android mini PC with Camera Review – Part 1: Unboxing and Teardown

Coowell V4 is one of the rare Android mini PCs with a built-in camera. It is powered by Rockchip RK3368 octa-core processor combined with 2GB RAM and 16GB flash. GearBest asked me whether I wanted to review it, and since I was curious about the camera, I took the offer up. Today, in the first part of the review I’ll start by checking out the device and its accessories, and tear it down to find more about the hardware design, before specifically testing the camera in the second part of the review in a similar way to what I did for HD23 review. Coowell V4 Unboxing The device comes in a black retail package with SMART MEDIA HUB text. The only icon that may cause troubles at custom might be the Android logo and text lacking TM. There’s also sticker on the side indicate Model: V4. SO there may be […]

Official Rockchip Github Account and Wiki Launched

Following the popularity of RK3066 and RK3188 processors in 2013, a community of developers for Rockchip Linux and Android development was created with corresponding linux-rockchip github account, mailing list and #linux-rockchip IRC channel, and now most of the information can be gathered from development board manufacturers like Firefly. However, I’ve just been pointed out to some VA-API driver for Rockchip RK32xx processor, on rockchip-linux (not linux-rockhip) github account, with the following tagline: An open source software for Rockchip SoCs, This site maintained by Rockchip The only person currently registered to this account, Jacob Chen (陈豪), is a software engineer working for Rockchip, so it does indeed look to be official. The github account also links to rockchip.wikidot.com with links to communication channels established by linux-rockchip community, and lots of entries about Linux, Android, U-boot, and so on, most of which are currently placeholders. So it still looks like work in […]

Coowell V4 is an RK3368 Android TV Box with a Retractable Camera

Coowell V4 looks like another typical Rockchip RK3368 Android TV box with 2GB RAM and 16GB flash, except for one little detail: it features a retractable camera to use with Skype, Google Hangouts and other video conference apps. Most Android mini PCs already claim support for USB UVC cameras, but in my past reviews I noticed that my camera were not always properly recognized in one or more apps, so in theory. the built-in camera is more likely to work with all app, since the company has (probably) tested it. Coowell “Smart Media Hub” V4 specifications: SoC – Rockchip RK3368 octa core Cortex A53 processor @ 1.5 GHz with PowerVR G6110 GPU System Memory – 2 GB DDR3 Storage – 16GB eMMC flash + micro SD card slot up to 32GB Video Output – HDMI 2.0 up to 4K60, and AV ports Audio Output – HDMI, AV, and optical S/PDIF […]

Linux 4.7 Release – Main Changes, ARM and MIPS Architectures

Linux 4.7 is out: So, after a slight delay due to my travels, I’m back, and 4.7 is out. Despite it being two weeks since rc7, the final patch wasn’t all that big, and much of it is trivial one- and few-liners. There’s a couple of network drivers that got a bit more loving. Appended is the shortlog since rc7 for people who care: it’s fairly spread out, with networking and some intel Kabylake GPU fixes being the most noticeable ones. But there’s random small noise spread all over. And obviously, this means that the merge window for 4.8 is open.Judging by the linux-next contents, that’s going to be a bigger release than the current one (4.7 really was fairly calm, I blame at least partly summer in the northern hemisphere). Linus Linux 4.6 brought USB 3.1 superspeed, OrangeFS distributed file system, 802.1AE MAC-level encryption (MACsec), and BATMAN V protocol support, improved […]

Linux 4.6 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.6 earlier today: It’s just as well I didn’t cut the rc cycle short, since the last week ended up getting a few more fixes than expected, but nothing in there feels all that odd or out of line. So 4.6 is out there at the normal schedule, and that obviously also means that I’ll start doing merge window pull requests for 4.7 starting tomorrow. Since rc7, there’s been small noise all over, with driver fixes being the bulk of it, but there is minor noise all over (perf tooling, networking, filesystems,  documentation, some small arch fixes..) The appended shortlog will give you a feel for what’s been going on during the last week. The 4.6 kernel on the whole was a fairly big release – more commits than we’ve had in a while. But it all felt fairly calm despite that. Linux 4.5 added […]
